These are 2 by 4 foot twin-wall polycarbonate panels sold in a set of 10, meant for greenhouse roofing, shed cladding, patio covers and DIY enclosures. The twin-wall build traps an air channel between two layers, which buffers temperature far better than a single sheet of the same thickness, and the panels pass up to 80% of natural light while blocking UV. Polycarbonate resists shattering and wind where glass would crack, and the sheets cut with a utility knife or saw for on-site fitting. Against glass they trade some clarity for toughness and insulation; against single-wall polycarbonate they insulate better but let slightly less light through.

These twin-wall polycarbonate panels are made for greenhouse roofing and other enclosure projects. Each panel has two layers with an air channel between them, which insulates and helps moderate interior temperatures. The panels are rated for temperatures from -44°C to 120°C (-47°F to 248°F).
The panels transmit up to 80% of natural light and block harmful UV rays. The high-strength polycarbonate resists shattering on impact and holds up against strong winds and extreme weather.
The panels are lightweight and can be cut to size with a utility knife or a standard saw. A protective film covers both faces to prevent scratches during shipping and installation. Uses include greenhouse roofing, garden shed cladding, patio covers, balcony partitions and DIY enclosures.
